Abstract
The utility model relates to a pipe joint comprising a joint core tube, a sealing ring, and a pressure ring sleeve, wherein the outer wall of the joint core tube is provided with a circular arc faying surface, when the pressure ring sleeve out of the joint is contracted after pressure, the jointed pipe line forms a higher jointing intensity and a better sealing effect at the faying surface of the joint outer wall. The utility model is suitable for jointing plastic pipes or plastic-aluminum multiple pipes, and has the advantages of easy assembling, high intensity, great sealing effect, easy processing and the like.
Description
The utility model belongs to a kind of pipe coupling, is adapted at aluminium-plastic composite pipe use when connecting is installed.
At present, aluminium-plastic composite pipe pipe coupling kind is a lot, most of thread type jointing that adopts, be a kind of old-fashioned conventional construction, the safety reliability aspect also can, but thread type jointing complex structure, the cost height, because the inipple unbalance stress leaks after application a period of time easily, give and use maintenance to make troubles.
For solving the deficiency of above pipe joint structure, the purpose of this utility model provides a kind of circular arc sealing pressure pipe joint, utilizes the circular arc joint to be added with seal ring, to reach easy for installation, to contact purpose firm, good sealing effect.
Structural design of the present utility model is achieved in that this circular arc sealing pressure pipe joint is by joint core pipe, seal ring and pressure ring tube are formed, its middle joint core tube wall is the circular arc junction plane, the outer support body is protruded for having bowl-type in the back, have circular groove in the support body, certain spacing of being separated by on the junction plane has the depression circular groove, stud with seal ring in the circular groove, be with the pressure ring tube in the outside of junction plane and seal ring, pressure ring tube bottom symmetry has peep hole, exert pressure at pressure ring tube external application machinery jig at last and form many horizontal indentures, make joint core pipe, become one by jointed tubular workpieces and pressure ring tube.
Advantage of the present utility model: the circular arc junction plane of being joined two pipes together at the pipe joint outer wall forms higher bond strength and better seal effect, prevents to produce between the different metal electrochemical corrosion simultaneously.
Structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a circular arc sealing pressure pipe joint structure schematic diagram.
Fig. 2 is that circular arc sealing pressure pipe joint connects the back sectional drawing.
Its structure as shown in the figure, 1 is joint core pipe, and 1A is the arc junction plane on the core pipe, and 1B is a circular groove, the placement seal ring is used, 1C is a circular groove on the support body of outer, and 2 is seal ring, can be rubber or plastics are made, 3 is the pressure ring tube, following 3A is a peep hole, and 4 is by jointed tubular workpieces, during installation, seal ring is put into circular groove on the core pipe, to take over be inserted above the core pipe again and be inserted into the end, the end connects with the outer support body, and the while is placed on the pressure ring tube on the core pipe, with alignd by jointed tubular workpieces, peep hole can be seen, exert pressure at the pressure ring tube with mechanical jig again, make pipe joint at last and be combined as a whole (as shown in Figure 2) by the adapter pressure.
Claims (1)
